Is there a way to get more detailed information on signal strength/connection status out over serial than I can with
SerialLogHandler logHandler (LOG_LEVEL_ALL);
I can’t get a Boron to connect to the internet, and it’s sitting in the same place on my desk that it had no problem with connected previously. I’ve tried flashing Tinker to it and it still won’t connect, so it’s probably not a problem in the software I’m running on it.
Is there some way I can view what it’s doing on the cell network?
I do know I’m not in a great location here - my cell phone reports an LTE signal strength of about -98 dBm, and I’m pretty sure its the same provider that particle is using (Telus)

and then it keeps going with “Still trying to connect to cellular”
I had a particle Boron that I hadn’t opened yet, so I tried setting that up and it works.
So what would the problem be here? Is it something on the carrier’s side where the boron is blocked from connecting? Did I break something on the Boron itself?
I don’t have specific experience with this, but this is in the documentation. If it had worked, now isn’t, I’d look into the possibility of what is described below:
You must not turn off and on cellular more than every 10 minutes (6 times per hour). Your SIM can be blocked by your mobile carrier for aggressive reconnection if you reconnect to cellular very frequently.
If you are manually managing the cellular connection in case of connection failures, you should wait at least 5 minutes before stopping the connection attempt. When retrying on failure, you should implement a back-off scheme waiting 5 minutes, 10 minutes, 15 minutes, 20 minutes, 30 minutes, then 60 minutes between retries. Repeated failures to connect can also result in your SIM being blocked.
